Try Bluezone “Electronic Masks”: There are two features, very easy to use, but the effect is due to you, me and us.

Tram Ho

The Bluezone application was launched a few months ago, but it was not until recently that it was really noticeable after a notice requiring people of Da Nang to install on the phone.

However, at present, not only in Danang but also in other cities and locations are recommended to use immediately to prevent and detect spreads quickly and easily.

Bluezone application is recommended by the Ministry of Information and Communications and the Ministry of Health.

Install and register

To install the Bluezone app, you need an Android or iOS phone. Then, go to the app store and search for the keyword Bluezone and then click download. Or, you can visit either link to download immediately.

The registration steps are also optimized for everyone to use immediately. Simply enter the phone number you are currently using, wait for the code message to be sent, enter the code into the application and you will move to the scanning step immediately.

Only 2 features

The Bluezone app has 4 tabs below, but only the home tab is useful and of interest. Here, you will see the main information about the application, the button to change the language to English, the number of people using Bluezone around and the daily exposure history.

Simple interface, easy to use, suitable for both the elderly.

In addition, the Notification tab only displays each line as “You have successfully updated the phone number” but no news about the disease situation as imagined. The Invite tab allows you to share the download link via message, email, other applications … Finally, the About tab includes information, details and contact the application development team.

How effective is it?

Testing to open Bluezone in some locations (To Vinh Dien, Truong Dinh …) in Hanoi has returned results of zero users. The high probability is because the current number of users is still too less, or download it but turn off Bluetooth / GPS go so the application does not recognize. Switch to see the number of remote users also do not see anyone.

Used for a few days, but the result is always 0. This is the number of people using Bluezone, not the number of people exposed to F0 patients.

If you go to the contact area close to F0 patients, the application will immediately send a notice to the machine and to the relevant ministries for solution.

Even in Da Nang – the current epidemic, we tried to open and click Scan around a few times but the results were still plentiful zeros, whether far or near.

The truth is, how effective Bluezone is, it’s still largely based on its number of users. And if no one uses this, then this app does not work at all.

Scanning nearby users still seems to be a “rarity” on Bluezone, not making up for Zalo.

It is unclear if this is a temporary application error, or if it is truly unused. Meanwhile, on the Android app market, the number of downloads of Bluezone has reached more than 500,000 and there are 3000 votes.

What are some issues to consider when using Bluezone?

The application requires permission to use Bluetooth and GPS at the same time to scan surrounding users. This makes the phone battery significantly reduced, especially when GPS is constantly on.

Bluezone promises this app doesn’t use much battery. This is true. Even if running in the background all day, Bluezone only takes about 5 – 10% battery is much. The actual battery drain is in the GPS connection, which can be up to 20 – 30% or more depending on the location of use and the device.

The application runs in the background for 3 and a half hours but requires only 0.5% battery. Use on Galaxy S20 Ultra, turn on optimal battery mode.

Bluezone explained that the app actually only needs to use Bluetooth Low Energy to operate but still has to turn on GPS, because this is a mandatory term from Google, not to track the user’s location.

If patient F0 has not used Bluezone before, the ability to detect exposure is zero. That is, in this case, Bluezone is completely useless.

This is how Bluezone works under ideal conditions, where everyone installs and uses it.

Therefore, the effectiveness of Bluezone is high or low, completely dependent on ourselves. The more people who use Bluezone now, the higher the likelihood of exposure detection. In addition, this information will also help the Ministry of Health and the Government to easily control the epidemic situation and devise appropriate solutions.
